Uses: This coloring agent is often used in food (such as candy) and personal care products, such as shampoos, hair dye, and even toothpastes. It is also commonly used in cosmetic products like lipstick.
Human Risks: Coal Tar Dye is often mixed with aluminum and other harmful substances making it even more dangerous. It is a proven carcinogen, can cause allergic reactions and asthma attacks, flu-like symptoms, inability to focus, and dermatitis (skin inflammation). Coal tar dye is also linked to the development of Alzheimers, and a faster progression of Alzheimers and other neurological diseases.
Environmental Risks: Coal Tar Dye can bioaccumulate, meaning that it can build up in the environment over time, causing harm to ecosystems. Chemicals that bioaccumulate are very difficult to eliminate from the environment, making it hard to reverse the damage. Like many of the chemicals on the list, they are especially harmful to aquatic life. It is also important to note that chemicals that build up in the environment often end up in our food sources and drinking water, causing further human harm.
How to Avoid: Unfortunately, coal tar dyes are often found in processed sweets such as M&Ms, so consider avoiding packaged sweets. It has also been shown that by reducing consumption candy and other heavily dyed food, concentration is improved. I know I keep repeating myself, but one the best things you can do is invest in your health by shopping at sustainable and ethical cosmetic and personal care companies. There are a ton of them out there, many of which I recommend on this site, so if you can afford it, make the switch!
